Six key points for late rice wet seedlings
The planting area of ​​late rice in Shanghang County in 2013 was 1,4764.7 hours, and planting and breeding were soon to begin. Late rice seedlings are in a high-temperature and rainy climate, and should be based on the fertility characteristics of selected varieties (combinations), combined with local safety during the full heading period and before the harvest period, appropriate sowing, moist seedlings, and cultivation. 1 The main varieties (combined varieties) selected are: Teyou 125, Teyou 627, No. 12 of Chuanyou, Shenyou 9775, Y Liangyou No. 1, II Youhang No. 2, II You 673, Youyou 62, Fufengyou 3301, Yiyou 99, Yiyou 673, Gangyou 527. New varieties (combination): Chuanyou 2189, Guyou 5138, Huayouyou 3301, Zhufengyou 3446, Yuyouyouzhan, Fuliangyou 366. Indica rice can choose Long 496. Ordinary farmers choose 2 to 3 good breeds, and large grain producers can choose more than one. 2 The preparations for the election should be made with convenient transportation, convenient drainage and irrigation, and are less susceptible to floods and floods. Can be weeded with chemical herbicides 5 to 7 days before sowing, and till 1 to 2 days before sowing to cultivate tilled soil. The content of N, P and K is 16-16-16 compound fertilizer, 10-15kg/667, which is used as base fertilizer. To achieve a smooth and smooth mud surface mud, less weeds, and smooth communication. 3 Normal sowing is generally selected in mid-June sowing, according to the amount of field use 0.8 ~ 1.0kg/667?, Putian sowing volume 10.0 ~ 12.5kg/667?, sowing has germinated seeds, dilute sowing uniform broadcast. 4 Anti-warm buds and murine birds and birds should be sowed after 16:30' on the same day. The area should be drained the next day. It can also cover the shading nets to protect against high temperature hot buds and birds. 3 to 5 days before sowing, the enemy rat salt bait was killed to kill mice around the field to be sowed. Promote the use of butyl sulfide carbofuran seed dressing mix 10g powder mix 1kg seed, that is mixed with broadcast. It can effectively control the pests of rice, horses and other pests and reduce the damage of rodents and birds. 5 to promote the control of high-yield seedlings seedlings grow to a leaf one heart period, drained Putian noodles water, using 15% paclobutrazol 150 ~ 200g/667? Watered 60 ~ 75kg spray. The long-term seedlings used more medicine, and the short-term seedlings used less, and after 24 hours of application, they were rinsed with water. Two-leaf and one-hearted, thin water application of three elements of compound fertilizer 8 ~ 10kg/667 ~ carbofuran 2.0 ~ 2.5kg. Keep shallow water ground irrigation. 6 Transplanting seedlings of suitable age, when they grow to 6.1-7.3 leaf age, they will be transplanted and transplanted, and 5~8 kg/667 urea will be applied 5 days before the seedling emergence. The artificial fertilizer will be applied in shallow water, using 20% ​​chlorantraniliprole and 75% tricyclic. The azole spray applied to the graft.
